MODERNIZING SYSTEM DEVELOPMENT: REQUIREMENTS-BASED, MODEL-DRIVEN DESIGN, IMPLEMENTATION, AND TEST

International audienceWith no end in sight, mechatronic system complexity continues to increase, worsening the challenges that have already plagued systems designers for years. Incomplete or volatile requirements, poorly specified and managed interfaces, integration testing finding problems at the very last stages of a program, development and analysis in disconnected domains, multi-domain expertise in short supply, and coordinating work and status across multi-level supply chains-these are all problems commonly discussed among systems developers. These challenges are further compounded in highly regulated domains, such as aerospace, automotive, and medical, where the end system must also be proven safe and conform to pertinent policy. In this paper, we discuss the root causes of system design challenges, and how the industry is responding with more effective design methods, tools, and collaboration mechanisms
